The main message of our quality guidelines hasn’t changed: Focus on the user.

Google’s webmaster guidelines are essential for anyone wanting to understand SEO. They describe what elements of a website Google’s search algorithm values and how to allow Googlebot to effectively crawl a site. The guidelines contain basic information that are valuable to someone just starting out with a new website.

The guidelines also contain technical information that advanced webmasters and developers should be aware of. One of the most notable updates includes expanded guidelines about rich snippets, which allow a website to provide additional information to Google. That expanded information may then show up in search results, which could encourage a potential client to click through to that site.
